A good PCB layout for the MAX17503ATP+ involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the high-current paths. A 4-layer PCB with a dedicated power plane is recommended.
Choose input capacitors with low ESR and high ripple current rating. For output capacitors, select ones with low ESR and high capacitance. The datasheet recommends a minimum capacitance of 10uF for the input capacitor and 22uF for the output capacitor.
The MAX17503ATP+ can operate in an ambient temperature range of -40°C to +125°C. However, the junction temperature should not exceed 150°C.
The MAX17503ATP+ has a built-in overcurrent protection feature. Connect a resistor (RILIM) between the ILIM pin and GND to set the overcurrent threshold. The device will limit the output current to the set threshold during an overcurrent event.
Yes, the MAX17503ATP+ can be used in a synchronous buck configuration. However, this requires an external high-side switch and a low-side switch. The datasheet provides a reference design for a synchronous buck converter.
